|
|
For example, `unzip ficl-4.1.0.zip` will leave the file
|
|
|
|
|
`interpreters/ficl/ficl-4.1.0`.

|
For example, `./configure.sh ficl-4.1.0` will leave the Makefile fragment
|
|
|
|
|
`Make.srcs` in the ficl build directory.

|
6. Configure and build NuttX. On successful completion, the Ficl objects will be
|
|
|
|
|
available in `apps/libapps.a` and that NuttX binary will be linked against
|
|
|
|
|
that file. Of course, Ficl will do nothing unless you have written some
|
|
|
|
|
application code that uses it!
